T o all whom t may concern.'

Be it known that I, ALFRED E. HOLMES, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Liquid-Dispensers, of which the following is a specification.

My invention relates to liquid dispensers, and the general object of the invention is to provide a simple and eiiicient device of this class, especially for the dispensing of liquid sqap in sleeping cars, toilet rooms and the 1i (e.

Among other more specific objects, it is my purpose to provide a positive acting -valve mechanism for delivering the liquid,

said valve mechanism to be capable also of measuring the quantity delivered at any full stroke of the valve. v

Another object is to provide a construe* tion such that the valve mechanism shall be self-cleaning.

I attain my objects by the mechanism illustrated in the accompanying drawings in whichv Figure 1 is a side elevation partly in central vertical section showing the assembled device. Fig. 2 is an elevation chiefly in eentral vertical section showing the valve mechanism. Fig. 3 is a top plan of the device.

' Fig. 4 is a plan section on the line 44 Fig.

1. Fig. 5 is a bottom plan section of the valve mechanism on the line 5 5 Fig. 2. Fig. 6 is a top plan section on the line 6-.6 Fig. 2.

Similar numerals refer to similar parts throughout the several views.

Referring to the drawings, the container l may assume any desirable form and is made preferably of glass and mounted upon any suitable support 2. At the top 0f the container is an externally threaded portion 3, onto which screws the similarly threaded cap4. This cap is preferably of sheet metal.

A notch 5 is formed at one part of the top for 'receiving the end of a locking arm 6 which is secured to a socket member 7 the flanges whereof receive between them the metal of the cap as best shown in Fig. 1. This socket member has a central socket 8 lwhich is polygonal, preferably square, for

receiving the nose of a, simple form of key.

The construction is such that the flanges of the parts from becoming displaced. As the socket 8 is closed at the bottom it prevents stances getting into the liquid and at the same time is free from projections which mlght catch 1n surrounding objects.

Referring now to the valve mechanism;

the valve casing 10 which contains the cylindrical valve chamber 11 is fastened in place by a nipple 12 which screws -into the valve casing and is externally threaded to take the nut 13. By preference washers 14 and 15 are placed above and beneath the bottom of the container for rendering the connection watertight. The nipple l2 has a longitudinal passage 16 which receives the stem 17 of the valve. A plunger 18 is formed at the lower end of stem 17, said plunger making a sliding it within the valve chamber. A plurality of ports 19 are formed in the perimeter of the plunger for permitting the liquid to pass. A valve seat 20 is formed at the bottom of the valve chamber and this receives the cone 21 formed on the valve stem beneath the plunger. Inlet ports 23 are formed in the sides of the valve stem at the upper end thereof for permitting the liquid to flow down into sirable that the outlet port-s 24 terminate above the lower end of the valve stem, thus permitting the lower end of the valve stem to aume a circular outline at the point 27 in order that the valve mechanism may be operated with greater comfort to the hand of the user.

Inoperation, under normal conditions the valve will remain seated as shown in Fig. 2. Under these conditions the valve chamber l1 will be closed -at the bottomA and the liquid from the container 1 will be permitted to flow down through the ports 28 into the said valve chamber. If now the operator presses upward upon the valve stem, the conical valve 21 will rise from its seat 20 and as soon as the upper end of the outlet ports 24 have reached the chamber, the liquid from said chamber will be permitted to flow down through the ports 19 in the plunger 18 and down through the outlet ports 24. The proportions are such,how ever, that the, ports 24 will not be uncovered until the ports 23 have been covered by the lower end of 'the nipple 12. In this way it is impossible for the liquid to iow straight through in a continuousflow no matter what the position of the valve stem may be.

When the operator releases the valve stem',

the spring 25 forces it and the plunger 18 down, thus forcing out the liquid from the valve chamber until the outlet ports 24 close. Of course Isome of the liquid beneath the plunger when the latter is in highest position will, when the plunger is descending How up through the ports or bypassesl9 so that only a portion of thecontents of the vchamber will be delivered at any one stroke.

From the foregoing, it will be seen that in ymy device the valve mechanism is very the passage.

simple in form, easy to disassemble, and

practically impossible of misoperation. The cover is simple and is practically smooth on top and yet may be' securely locked b'y the application of. a simple :form of key. Furthermore, the valve mechanism is selfcleaning. As the plunger fits the sides of the chamber, it scra es them every time 1t moves vertically. -'l` -s is of great lmportance for it will'be understood by those familiar with soap `dispensers, for example, that the soap tends'to harden andalso to form verdigris on the sides ofthe chamber. If' the plunger were simply a disk of smaller diameter than the inside -wall of the chamber and depended for the resulting annular space for the passage of the liquid, the soap would soon build up on the walls and choke In my construction the pa ssages are formed by actual notches or ports ofopen shape andfithe walls are continually` being scraped. As there is nothing to pre vent the plunger from rotating, it gradually doesso under the action of the hand of the -operator and hence the ports angularly from time to time .and permit all parts of the wall to be cleaned.

lHaving thus, described my invention, what ters Patent, is:

1. Ina liquid dispenser, a container, a cy- I lindrical valve stem having a plunger between its ends, and longitudinal grooves in passages, said valve stem having a valve seating upon said receptacle at the lower end thereof, and the plunger, when the valve is seated, being elevated above the lower end of said chamber.

2. In a liquid dispenser, the combination of a container, a valve stem having a plunger located between its ends, said plunger having an aperture for the passage of liquid, aseparable nipple secured to the bottom of said container,'said nipple having a passage in which the upper portion of the valve stem fits slidingly, a valve casing securedto said nipple, said valve casing having a chamber in which the said plunger fits slid'- ingly, said valve casing having a passage at the lower end of thedchamber in which the portion `of the valve stem below the plunger fits slidingly, said stem having a longitudinally .grooved port above and a similar port below said plunger for the passage of liquid into and out of the valve chamber.

3. In a liquid dispenser,-the combination of a container, a cylindrical valve stem havin which the upper end of the 'valve stem vfits slidingly, a valve casing screwing onto said nipple, and containing a valve chamber in which said plunger makes a close sliding fit, said valve casing having a passage at the bottom in which the lower end of the -valve stem -its slidingly, said valve stem having, ports above and below the plunger 4. In a liquid-dispenser, the combination of a container having a cylindrical chamber beneath it, there being a cylindricalpassage leading downward from the con# tainer to the chamber and another cylindrical passage leading down andout from the bottom of said chamber, said passages being in line with each. other, a plunger fitting slidinglyin said chamber and'havingnotc'hes formed in the 'edges thereof which constitute ports, a valve stem extending upward from the plunger into the first mentloned ideama passage and another stem extending downward from the plunger into the second mentioned passage, the upper stem having inlet ports formed in the side and the lower. stem having outletyports formed in the side, substantially as described.

5. In a liquid dispenser, a container, a cylindrical valve stem having a plunger between its ends, said plunger having "notches in its periphery, and said stem having ports in its side above and below said plunger, a

cylindrical chamber beneath said container, said plunger fitting slidinglywithin said chamber, a cylindrical duct at the top of the chamber leading thereinto from the container, a cylindrical duct 'at the bottom of said ehamber,.in line with the first mentioned duet, said ducts making al sliding t with said valve stem, and a spring tending to force said plunger downward, said plunger and stem being free to rotate.

ln witness whereof, ll have hereunto subscribed my name in the presence of two witnesses. v
